Cannabinoid Hyperemesis Syndrome: An Under-Recognized Diagnosis

With the growing spread of cannabis abuse, a novel clinical disorder has emerged, termed Cannabinoid Hyperemesis Syndrome (CHS). Researchers in Israel published a Case Communications report in the Israel Medical Association Journal in May 2015. The majority of patients with CHS are heavy users of cannabinoids, on a daily or almost daily basis for years. Symptoms are characterized by recurrent attacks of severe nausea and vomiting and accompanying abdominal pain. Users compulsively take hot baths to ease the symptoms. Cessation of cannabis use will result in complete resolution of the symptoms.
